Abstract

L~invention concerne un système générateur de puissance électrique en fond de trou comprenant un dispositif limiteur d~écoulement (48) qui limite de façon variable un écoulement à travers une ouverture (40), le dispositif limiteur vibrant en réaction à un écoulement à travers l~ouverture et le dispositif limiteur augmentant et abaissant ainsi en alternance l~écoulement à travers l~ouverture ; et un dispositif générateur d~électricité (54) qui génère de l~électricité en réaction à la vibration du dispositif limiteur. Un autre système générateur de puissance électrique en fond de trou comporte un dispositif limiteur d~écoulement qui vibre en réaction à un écoulement à travers une ouverture, le dispositif limiteur augmentant et abaissant ainsi en alternance l~écoulement à travers l~ouverture, un différentiel de pression de part et d~autre du dispositif limiteur polarisant de manière variable le dispositif limiteur pour limiter progressivement l~écoulement à travers l~ouverture.
